sna: Reorder frontbuffer resize vs flip event queue draining
If we are not careful, we may process an unflip in the middle of
resizing the frontbuffer - when the ScreenPixmap state is ill-defined.
First flush all the pending flip events, cancel any residual unflips,
then update the screen pixmap. This should be enough to close the race.</pre>
